Wireless Media Access Controller (MiMAC) and Microchip Wireless Application Programming

Interface (MiApp), as described in Application Notes AN1283 and AN1284. A Quick Start Guide is

included in the software installation package that explains the installation and operation of the

demonstration program. The Quick Start Guide is available for download from the Microchip web

site http://www.microchip.com/wireless.

The MRF24J40 Radio Utility Driver Program provides design engineers a development and testing

utility program that operates on the PIC18 Explorer Board (DM183032) and for 16-bit and 32-bit

microcontroller development using the Explorer 16 Development Board (DM240001). The program

is available for download from the Microchip web site http://www.microchip.com/wireless , and

detailed information is given in the Application Note AN1192.

Operation

Programming and configuration options for the MRF24J40MC transceiver modules are provided

in the MRF24J40 IEEE Std 802.15.4 2.4 GHz RF Transceiver Data Sheet (DS39776) . Sample

source code is the best place to start. Refer to the compile options when enabling the

MRF24J40MC transceiver modules.

IMPORTANT

The MRF24J40MC module contains a power amplifier (PA) and low noise amplifier (LNA). It is impor-

tant that the MRF24J40 be configured to control the PA and LNA. Refer to Section 4.2 External PA/

LNA Control in the MRF24J40 IEEE 802.15.4 2.4 GHz RF Transceiver Data Sheet (DS39776).

When using the sample source code, refer to the compile options to enable the PA and LNA.

CAUTION

Voltage and current to the MRF24J40MC PICtail?/PICtail Plus Daughter Board should be in the

range of 2.7V – 3.6V and capable of supplying 120 mA. Ensure that the daughter board is plugged

into a development/demonstration board that meets this power requirement; otherwise, damage to

the MRF24J40 may occur.

Power Disconnect/Current Measure jumpers (JP1/JP2) – Two 2-pin headers are connected in

parallel. A shunt on one of the two headers connects power to the MRF24J40MC module. A

current meter can be placed on the open header and when the shunt is removed from the

opposite header, current consumption can be measured without interrupting power. A useful

cable that can be connected to the 2-pin header and current meter, using banana plugs, is the

XLP Current Measurement Cable (AC002023).

INT2 Jumper (JP3) – For the PIC18 Explorer Board, jumpering JP3 with a shunt allows the

connection of RA5 to RB2/INT2 and enables push-button switch S2 to trigger an interrupt.
